System Information
Operating system: Windows 11

Worked: (First time trying multires hasn't worked on any of the versions I've tested on)

Short description of error

Crash on sculpt mask brush when Multiresolution modifier is copied from another object.

Exact steps for others to reproduce the error

Replicate problem 1:

  • Add a Cube (#1)
  • Add Multiresolution modifier to Cube (#1)
  • Subdivide 4 times
  • Add a Cube (#2)
  • Copy Cube (#1)'s modifier onto Cube (#2) through the use of Link/Transfer Data > Copy Modifier
  • Select Cube (#2) and enter sculpt mode
  • Select Mask Brush
  • Use Mask Brush (Should crash blender)

I can still reproduce this but I got the crash on using the mask brush on Cube #1 instead.
This only seems to happen if no mask was created so far.

Still happening in 3.3.16 (but was fixed in 3.4.0)

Will check if I can quickly find a commit that could be backported (so added to #100749)
